EIC eligibility, forgot if I received a notice from IRS

I just got done filling taxes and qualified for the EIC. I saw the question on TurboTax asking if I've received a letter of denial from the IRS. This reminded me I did receive something from them in the past. I can't remember if it was for this year, but was regarding a credit (likely child credit or EIC).

I couldn't find that letter anywhere. From what I can tell, I should qualify based on eligibility. TurboTax program told me the IRS will likely make changes if I'm not eligible. 

My taxes were accepted by the IRS. Should I be confident I will keep the EIC or maybe get a notice to amend?
